Heat olive oil in a large skillet over medium-high heat.
Add sliced chicken breast to the skillet and season with salt and pepper.
Cook until the chicken is golden brown and cooked through, about 5-6 minutes.
Remove chicken from the skillet and set aside.
In the same skillet, add minced garlic and ginger; sauté for 1 minute.
Toss in the broccoli florets, bell pepper, and snap peas.
Stir-fry the vegetables for about 3-4 minutes until they are tender-crisp.
Return the cooked chicken to the skillet.
Pour soy sauce over the chicken and vegetables, stirring to combine.
Cook for an additional 2 minutes, ensuring everything is heated through.
